This Study focuses on the preparation of sustainable and efficient Chitosan catalyst for removal three organic pollutants, 17β-Estradiol (E2), 17α-ethynyl estradiol (EE2) triclosan (TCS) from water. The prepared nanocomposites were characterized by different techniques which confirmed presence key components Chitosan, Carica Papaya seed Kaolinite. optical characterization proved nanocomposite is photoactive with a band gap 1.81 eV 1.77 Chitosan/kaolinite biochar (CS/KBC) biochar/GO (CS/KBC/GO) respectively, confirming ability to be active in visible light region spectrum. degradation experiment using CS/KBC/GO was observed better 100% 5 mg/L E2 EE2 over 60 min 97.8% 120 10 TCS at optimum conditions (pH 3 E2, pH 7).

Innovative low-cost magneto-biochar-clay (MBC 1:2:1 and MBC 1:3:1) composite adsorbents formed by a one-step combination of magnetic nanoparticles (MNP), biochar (from grape cluster stalk), feldspar clay were employed for Cd(II), Cr(VI), Cu(II) removal from simulated contaminated aqueous solution. The composites expressed higher cation exchange capacity BET surface area compared to the clay, as well characteristic biobased functional groups such hydroxyls, carboxyls, amides. optimum efficiency was achieved at 0.66 g/L solid-to-liquid ratio, equilibrium attained 720 min all three ions. adsorption process via electrostatic interactions within pores (>90% total adsorption). Surface involved in are -OH, -COO-, -C-N. An increase concentration solution enhanced Cr(VI) 86 79% on 1:3:1, respectively, while reducing Cd(II) uptake 65 52%, respectively. data described Langmuir Langmuir-Freundlich isotherm models. Higher temperature slightly adsorption, no impact observed adsorption. adsorbent reusability study confirmed that remained high after five cycles, only during first cycle. Thus, is cost-effective efficient and, due its properties, can easily be applied water treatment water.

A zirconium-based metal–organic framework (UiO-66-NH2) was fabricated, which then hybridized with TiO2. The synthesized adsorbent utilized for the adsorption of ampicillin (AMP) and lead (Pb(II)) from an aqueous solution. main characterization analyses including Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), N2 adsorption/desorption isotherms, thermogravimetry (TG), energy-dispersive spectroscopy (EDS), elemental mapping, transmission electron microscopy (TEM), field-emission scanning (FESEM), water contact angle, XPS affirmed correctness synthesis. nanocomposite UiO-66-NH2/TiO2 had a high crystallinity, surface area (1050 m2/g), stability up to 600 °C. Adsorption experiments were performed explore different parameters affecting adsorption. results revealed fast kinetics this adsorbent. majority AMP Pb(II) adsorbed in 30 min, pseudo-second-order kinetic model better agreement empirical data (R2 ≥ 0.993). Furthermore, Langmuir isotherm 0.987) fitted compared Freundlich 0.920). maximum capacity 625.7 mg/g gained 769.2 (pH 7 ± 0.1 T = 300 1 K), 1.3 1.5 times greater, pristine UiO-66-NH2. thermodynamic study demonstrated that process AMP/Pb(II) by is spontaneous exothermic. allocated area, large number active sites, hydrogen bonding, hydrophobic forces, electrostatic interactions, π–π interactions. Finally, acceptable reusability five regeneration cycles. With its sustainable easy fabrication, remarkable performance, excellent capability, emerges as highly effective industrial wastewater treatment applications.
